Boiler Efficiency Analysis Using Direct Method

Abstract

Real-time data of boiler thermal efficiency can really reflect the boiler operation condition, heat generation and heat loss. Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Boiler efficiency can be also useful in analysis of boiler and can also be used in predictive maintenance of the boiler. How to reduce problems of the boiler efficiency real-time computations and be successful in calculating the boiler thermal efficiency on line are the main concern of operation departments of power systems. In this paper direct method (i.e. input -output method) is explored for boiler calculation of boiler efficiency. Using Heat Input-Output method plant people can evaluate quickly the efficiency of boilers using few parameters
